Pretty cool. The Sampan Express 19 is a favorite of mine, and I have never seen those drawings. The design number is barely legible, either 186 or 185. The Texas Dory 8 1/2" x11" plan sheets call this the Texas Dory 19. (I just updated it to the design index, totaling 562 known designs.)

The 44 footer from Yachting Magazine 1965 I believe is called Mediterranean Express
